Oarhead
They live for rowing, and if you don't talk about it, they'll yell at you. They think they're the best rower ever, even if they're the last one to finish the race. They'll cuss you out for not knowing the difference between a scull and a shell.
'I swear, if you don't talk about rowing, I'm gonna cuss you out in front of the whole team.'
'I'm the best rower ever. You're just a benchwarmer.'
'You don't know what a scull is? I'm gonna fail you in life.'
